Firstly, you need to make sure that you are connected to a 2.4GHz network. If you are not sure what your network is, you can follow this:If your router supports both the 2.4 GHz and 5 GHz bands, but only one Wi-Fi name is displayed on the Wi-Fi search page of your mobile phone, perform these steps:
1. Go to the wireless page of the router. (The entry address is usually provided on the label attached to the back of the router).
2. Go to the 2.4 GHz setting page, and set the Wi-Fi name (SSID) to XXX—2.4G, where xxx indicates the Wi-Fi name. Save setting.
3. Go to the 5 GHz setting page, and set the Wi-Fi name (SSID) to XXX—5G, where xxx indicates the Wi-Fi name. Save setting.When the preceding settings are complete, the new Wi-Fi names will appear on the Wi-Fi settings page of your mobile phone.
Note: After the Wi-Fi names are changed, you need to reconnect the devices that use this wireless router. The password remains the same if it has not been changed.It is recommended that you use the AP mode (the AP mode will automatically select the 2.4GHz network for connection), and then add it again. If you can connect to the device but have problems, you can provide us with the device ID. Thank you for your understanding and support!
